In Singapore, power trips are a frequent electrical emergency faced by homeowners. This occurs when the current in a circuit breaker exceeds the prescribed amount, thereby cutting off the electric supply. 

Although a power trip prevents damage to the wiring and other appliances, it can also result in a blackout. So to prevent it, here are some reasons why a power trip may occur in your circuit breaker and how you can resolve it. 

3 Reasons Why Circuit Breaker Keeps Tripping

Overloaded Electric Circuit

One main reason why a power trip happens is because of the electrical circuit getting overloaded beyond the prescribed limit.  When the current exceeds the rated capacity of the wiring, it can get damaged or create a fire hazard.  In order to prevent an actual fire from taking place, a circuit trip occurs. 

Connecting multiple electrical appliances to a power supply may also cause the power supply to trip. Malfunctioning appliances in particular may use up more power, increasing the total current supply and causing the circuit breaker to trip.

Short Circuit

A short circuit can also cause an HDB circuit breaker trip . One way to identify this is by checking for burning smells. Usually, a Short circuit occurs when the hot wire (black) touches a neutral wire (white).  A surge in current supply can also happen when electrical wiring with damaged insulation come into contact with each other. Damaged appliances or lighting components with wiring problems can also cause a short circuit when plugged into an outlet.

Ground Fault 

Besides short circuits, a power trip can also happen because of a ground fault. . When the circuit breaker’s hot wire comes into contact with the ground, the resistance is lowered and causes increased current.  A hot wire (black) which makes contact with a metallic object can also cause a circuit breaker trip to occur. 

Ground faults can also happen when homeowners ignore general electricity safety tips . Furthermore, this can cause a highly dangerous accident such as an electrical shock from switches or sockets . 

How to Fix a Power Trip

Overloaded Electric Circuit 

• Firstly, switch off all electronic appliances, gadgets, and light installations in the house.
• Next, switch on  all low power consumption electrical devices.  
• Now turn on your high power consumption appliances gradually until an electric trip occurs. Note down which high power consumption devices were connected when the trip happened.
• Whichever appliance has caused an increase in the power supply is likely to be the cause of your power trip.
• After determining the cause of your power trip, you can Connect the high power consumption electric appliance to another electric circuit to avoid another electric trip.
• Alternatively, you can upgrade your electrical wiring and hardware to carry the additional power load. While waiting for the wiring to be upgraded, you should minimize the use of appliances that consume more power as much as possible. You can also switch off all other appliances when only one is being used.

Compared to a power trip caused by overloading, fixing one which results from a short circuit is usually more difficult.

Usually, in the case of a short circuit, there is a massive spike in current which results in burning (causing a bad smell and discoloration). In that case, the electrical outlets should be switched off, and each of the power points and sockets should be inspected for any discoloration or smell. The insulation of the wiring should be checked as well. Furthermore, all the appliances should also be inspected for damage or odor. Usually the appliance with a short circuit will stop working and will have to be replaced or repaired.

Since most homes and offices have concealed wiring , it is not easy to inspect the wiring for damage or short circuit. Moreover, it is not easy to find out the exact condition of the wiring to detect any damage which has occurred. 

During monsoon seasons, an increase in the moisture levels or wet walls may cause a short circuit. Unfortunately, most property owners do not have the tools and experience to detect the damage to the concealed wiring. Hence it is advisable to hire the services of a licensed and experienced electrician who can accurately detect the short circuit and conduct an electrical wiring repair or replacement.

• Switch off all appliances and unplug them from the electric circuit.
• Switch on the circuit breaker .
• If there is no electric trip, each of the appliances should be connected to the circuit. Once the defective appliance is connected, the circuit breaker will trip.
• The faulty appliance should be repaired or replaced to prevent another ground fault.

If the circuit breaker continues to trip, it’s p o ssible that you might have electric wiring mistakes present. In that case, you should contact a reliable electrician to check the wiring and fix it if needed.

Depending on the cause of the electric trip, the property owner can either fix it himself or hire the services of a well-trained licensed electrician in Singapore.  If you opt for the latter, you can contact someone from Daylight Electrician Singapore  with many years of experience in providing all kinds of electrical services .

What You Need to Know

• A tripping circuit breaker could be a sign of an overloaded circuit, a short circuit, a ground fault, or a worn-out breaker.
• Homeowners will want to hire an electrician to determine the cause of the frequently tripping circuit breaker.
• Electricians may recommend replacing the circuit breaker, installing GFCI outlets, or rewiring part or all of the home.

Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

• Buzzing noises coming from outlets
• Devices charging slowly
• Electrical outlets not working
• Flickering lights
• Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

• Popping sounds
• Discolored outlets or switches
• Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

• Tripped GFCI (ground fault circuit interrupter) outlets;
• A burning smell coming from an outlet; and
• Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

• The circuit breaker getting hot and tripping frequently;
• The circuit breaker won’t reset;
• It has been over 10 years since the breaker was last serviced; and
• The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

Power Tripped? Common Causes and What to do

by Peter Cardamone | Oct 2, 2020 | Domestic Electrical , Emergency Electrical | 0 comments

Having something trip the power in your home can be an extremely frustrating occurrence – especially if you’re in the middle of a task, and particularly if you don’t know what has caused it. Often, the problem may be simpler than you think. There are a few reasons why your power might have tripped. Even better, there are simple steps to follow to fix the problem quickly and easily, allowing you to get on with your day.

Causes of a Power Trip

Essentially, a power trip occurs when the electrical system in your home is compromised in some way. The trip is a safety mechanism, meaning your circuit breakers will ‘trip the switch’ and automatically shut down power to one or several systems, making sure the problem cannot become anything more serious. This can happen for a number of reasons.

Overloaded Circuit

The most simple cause of a power trip is an overloaded circuit. If you have too many devices or appliances running simultaneously, the circuit can end up drawing more electrical load than it is equipped to handle. It heats up, the circuit breaker senses this, and the power trips before the circuit can heat to a dangerous level.

Short Circuit

A short circuit can be caused by a wiring problem in a device or an appliance when it is connected to your main system. It can also happen if two opposing wires accidentally touch, causing an unexpected surge of electricity that will cause the circuit breaker to trip the system.

Earth Leakage Fault

An earth leakage fault is a type of short circuit, and it will happen when the current flowing through the electrical system finds an alternative path other than the active or neutral conductors. These are slightly more dangerous, particularly if they occur in places such as the bathroom or kitchen where moisture could carry the electricity and cause shocks. Once again, the increase in electricity will cause the circuit to heat up, and the circuit breaker will therefore initiate a power trip to prevent further damage.

What to Do About a Power Trip

In the case of a short circuit or a ground fault, it is advisable to promptly seek professional advice in order to resolve the problem safely. If you live in the south-east, you may want to call your electrician in Brighton and get a specialist to take a look at the problem. However, in the case of an overloaded circuit, you can often fix the problem yourself in a few simple steps.

Before any fault occurs, it’s useful to ensure you know where your electrical board is located, and you have a handheld torch to help you navigate in case of a blackout.

Turn Appliances Off

Make sure to turn any appliances off that are connected to the affected system.

Master Switch

At the power board, your first move should be to turn off the master switch. This will ensure you cannot get hurt whilst fixing the problem.

Safety Switch

Make sure you have an RCD safety switch installed , and use it to check the safety of your appliances.

Once you have flipped the relevant switch back to the ‘on’ position, test that the circuit is working again. If it is not, or if it immediately trips again, it may be that the problem is more severe than an overloaded circuit, and it’s time to call in the professionals.

Key Takeaways

• Identifying the cause of a tripping circuit breaker is crucial for safety and system integrity.
• Resetting a tripped breaker involves following proper steps to ensure electrical safety.
• Knowing when to consult a professional electrician is important for troubleshooting complex circuit breaker issues.

Understanding Circuit Breakers and Their Function

In this section, you’ll learn precisely what a circuit breaker is and how it functions as a safety mechanism to prevent electrical fires.

What is a Circuit Breaker?

A circuit breaker is an automatic electrical switch designed to protect an electrical circuit from damage caused by excess current resulting from an overload or short circuit. It works by interrupting the flow of electricity upon detecting a fault condition. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation.

How Circuit Breakers Prevent Electrical Fires

Circuit breakers play a crucial role in maintaining your safety by mitigating fire hazards. If an electrical overload or short occurs, a breaker will “trip”, effectively cutting off power to the affected circuit. This interruption in electrical flow stops excessive current that can cause overheating, which if left unchecked, could result in electrical fires. By acting as a safeguard, circuit breakers help to preserve both your electrical system and your physical safety

Reasons for Circuit Breaker Tripping

When your circuit breaker trips, it’s often due to preventable electrical issues within your home. Understanding why this happens is the first step in addressing the problem.

1. Overloaded Circuits

Overload occurs when you demand more electrical power from a circuit than it can handle. Common signs of an overloaded circuit include appliances that seem underpowered or lights that dim when you use other appliances. To rectify this, try:

• Unplugging unnecessary devices to reduce the electrical load.
• Spreading high-energy appliances across different circuits.

2. Short Circuits

A short circuit is a more serious issue marked by two wires touching that should not—an occurrence potentially hazardous and a common reason for tripping . This can result from a variety of issues including damaged wires or faulty appliances. If you notice a burning smell or scorched outlets, the next steps include:

• Powering off the circuit.
• Inspecting your appliances and wiring for damage.
• Seeking professional help if you’re not experienced with electrical work.

3. Ground Faults

  Ground faults are similar to short circuits but involve a hot wire touching a ground wire or metal box. They often occur in areas at risk for moisture intrusion, such as kitchens or bathrooms. Manage ground faults by:

• Testing GFCI (Ground Fault Circuit Interrupter) outlets regularly.
• Keeping appliances away from water sources.
• Consult with an electrician to ensure proper grounding of all outlets.

4. Power Surges

External power surges due to lightning or changes in the power grid and internal surges, when high-power appliances turn on and off, can trip breakers.

5. High-Power Appliances

High-power appliances like microwaves, hair dryers, and air conditioners can trip breakers, particularly if other devices are used on the same circuit simultaneously.

How to Properly Reset a Tripped Breaker

If you’re faced with a tripped breaker, it’s crucial to approach the reset process with a focus on electrical safety to avoid hazards. Ensuring you follow the proper steps can safeguard both your well-being and your home’s electrical system.

Assessing the Safety Before Resetting

Firstly , verify that there is no apparent danger in your surroundings. If you notice any unusual signs, such as scorch marks on outlets or a burning smell, do not attempt to reset the breaker; instead, consult a professional electrician. Additionally, ensure that the area around your electrical panel is dry to prevent the risk of electric shock.

Step-by-Step Reset Process

follow these steps to reset your tripped breaker:

• Identify the Tripped Breaker : Look for the breaker that is positioned in the middle, indicating that it has tripped.
• Unplug Devices : Before resetting, unplug all devices connected to the tripped circuit to prevent further overload when the power is restored.
• Reset the Breaker : Flip the tripped breaker firmly to the ‘Off’ position and then to the ‘On’ position.

By taking these measures, you can reset your breaker safely and effectively. Remember to always prioritize safety when dealing with electrical issues. If the breaker trips again after you have reset it, or if you are unsure at any stage, it is essential to contact a qualified electrician.

Preventive Measures and When to Call a Professional

To ensure the safety and reliability of your home’s electrical system, adopt a proactive approach. Regular maintenance can prevent circuit breaker issues while recognizing when professional intervention is necessary can save you from more extensive problems.

Regular Maintenance and Inspections

Conducting regular maintenance on your electrical system is pivotal to preventing unexpected circuit disruptions. At least once a year, inspect your electrical wiring, looking for signs of wear and tear. Test safety devices like GFCI outlets periodically to confirm they’re functioning properly.

Upgrading Your Electrical System

If your home is older, it may be time to consider upgrading your electrical system. This could include replacing old wiring that can’t handle modern electrical loads or adding additional circuits. Upgrades provide not only enhanced safety but also improved functionality for your everyday power needs.

What to Do if Circuit Breaker Still Keeps Tripping?

What is a circuit breaker (and why does it trip).

An electrical circuit breaker is a switching device that can be operated automatically or manually to control and protect the electrical power system and the electrical devices connected to it.

The circuit breaker trips when too much electricity flows through it or when it cannot handle the excess current load. In layman’s terms, this situation is called an electricity trip. It means that the flow of electricity is cut off to keep your circuits from overheating or causing more damage.

If there had been no electric trips, house fires would have been quite common. Read on to learn more about this critical electric safety topic!

If there is frequent tripping in your circuit breaker, it indicates something is going wrong with the circuit. There may be a short circuit in one of your appliances or a ground fault. Maybe there is a circuit overload or a sign indicating the circuit breaker box is faulty. Keep an eye out for all of these reasons, especially if your main breaker keeps tripping .

If you know what causes a circuit breaker to trip , you can take action to prevent it from happening again. Let’s delve into 6 main reasons that cause circuit breakers to trip frequently(and it’s troubleshooting).

Overheating Appliance

Circuit overload.

A circuit overload occurs when you want a particular circuit to provide more electricity than its actual capacity. This leads to overheating the circuit, which puts all the electrical appliances connected to the circuit at risk.

For example, suppose your television is connected to the circuit, which actually needs 15 amps but is now using 20 amps. In that case, the circuit of the television system can get fried and damaged. The circuit breaker trips to prevent this from happening, potentially even preventing a significant fire.

It’s vital to identify the overloaded circuit, switch the tripped breaker back on, and then carefully plug your appliances back in. Try to redistribute your electrical devices and keep them off of the same circuits as recommended by fellow electrical repairmen.

Short Circuits

Another common reason why power keeps tripping is a short circuit . It’s more dangerous than an overloaded circuit. A short circuit is caused when a “hot” wire comes into contact with a “neutral wire” in one of your electrical outlets. When this happens, a large amount of current flows through the circuit, creating more heat than what the circuit can handle.

Ground Fault Surges

Generally, arc faults is also considered to be a major reason behind frequently tripped circuit breakers. An arc fault happens when loose or corroded wires create a short contact that causes an arc or a spark. This creates heat and can risk an electrical fire. If you hear your light switch hissing or the outlet buzzing, you are experiencing an arc fault.

Defective Circuit Breaker

What if you find out that the reasons mentioned above are not why your circuit breaker keeps tripping ? Well, in that case, maybe your circuit breaker is at fault. When the breaker is old and cannot produce electricity anymore, it’s time to replace it. Also, a breaker is bound to wear out if not maintained.

How to Find What is Tripping my Circuit Breaker?

When a circuit breaker trips, it means there is an electrical problem that needs to be addressed. To find out what is causing the breaker to trip, follow these steps:

• Turn off all the devices and appliances that are connected to the circuit that is tripping the breaker.
• Reset the circuit breaker by flipping it to the “off” position and then back to the “on” position.
• Turn on each device one at a time and see if the breaker trips again.
• If the breaker trips when a specific device is turned on, unplug that device and try plugging it into a different circuit.
• If the breaker does not trip when the device is plugged into a different circuit, then the problem is likely with the original circuit.
• If the breaker continues to trip even with all devices and appliances unplugged, the problem may be a short circuit or a faulty breaker.

If you are not comfortable with or qualified to deal with electrical issues, it is best to contact a licensed electrician to diagnose and fix the problem.

If a circuit breaker keeps tripping even after trying the troubleshooting steps mentioned earlier, it’s best to get in touch with an electrician and have them look into it. In the meantime, for your safety, you can also try inspecting it yourself using these methods with appropriate caution.

• Unplug Devices: Manually switch off any devices and then unplug them. This is necessary because once the power surges back and the devices are still on, it might affect them adversely.
• Reset the Circuit Box: Go to the circuit breaker and switch it off or remove the fuse. Turn it on again. This is how you reset a circuit breaker .
• Check the Reasons: Inspect the circuit box again and check whether any of the above reasons tick the current situation of your circuit breaker.
• Switch on the Devices: You need to test the circuit by switching on all the lights and appliances you unplugged. This gives you an idea of what is causing the breaker to trip.
• Check or Replace: Once you check all the devices, decide whether you need to replace the circuit breaker with a new one. It is critical to treat electrical issues carefully. If your circuit breaker keeps tripping , it means something isn’t right. Understanding why it is happening frequently and how to diagnose and cure this problem can help you keep your house safe and prevent damage. However, it is always advisable to call a licensed electrician if such issues persist.

Conclusion:

A tripping circuit breaker is a warning sign that something is amiss within your electrical system. Understanding the basics of how circuits work and simple troubleshooting can help you pinpoint easy fixes. As mentioned earlier, electrical issues can be complex. Contact a qualified electrician when dealing with repeated trips.

Circuit breakers exist to protect people, appliances, and homes from dangerous electrical current. However, few people understand why the trip and how they operate. Master electrician Heath Eastman shows host Kevin O’Connor why this happens, and even explains a few different types of breakers.

All About Electrical Systems

Breakers Protect Circuits

When electricity comes into the house, it flows through the electrical service panel. From there, the electricity flows out through different branches in the house, each controlled by a circuit breaker. Should a branch begin to overload and overheat, the breaker will trip to prevent damage.

Breaker Sizes

There are two main sizes of breakers in a house: 15 amp and 20 amp. The amp rating explains how much current the breaker can handle before it will trip, and each requires a certain size of wire. Fifteen-amp breakers require a 14-gauge wire, while 20-amp breakers require a 12-gauge wire.

How They Work

A 15-amp breaker won’t necessarily trip the moment it experiences a spike above 15 amps. Many devices draw more amps upon start-up, and these breakers allow those temporary spikes. However, should the breaker sense elevated amperage for longer than is typical, it will trip to prevent the circuit from overheating.

GFCIs and AFCIs

Beyond circuit overload protection, there are other types of breakers that offer additional coverage. These include GFCI breakers and relatively-new AFCI breakers .

GFCI (ground fault circuit interrupter) breakers need to experience the same amount of current going out as coming back through the circuit. If the breaker experiences a drop in returning current, it assumes that the circuit is leaking, whether it be through a water source or a person. When this imbalance occurs, the GFCI trips immediately.

AFCI (arc fault circuit interrupter) breakers sense when the circuit, a device, or an appliance is arcing (the current is jumping from the circuit and onto something else or someone). When the breaker recognizes the arc signature, it trips immediately. These breakers are relatively new and look similar to GFCI breakers, but they’re becoming a code requirement in most locations.

How to Test Breakers

Homeowners, electricians, and inspectors can test their breakers. There are devices that users can plug into an outlet and replicate an error. These devices, known as AFCI/GFCI testers, can trip the breaker altogether or replicate a ground or arc fault, triggering the breaker. This is one of the best ways to ensure that a breaker is working properly.

When to Call a Professional

If a circuit is continuously tripping, or you know that it should be tripping and isn’t, be sure to call in a professional. An electrician will be able to determine the cause of the issue and make sure your circuit breakers and electrical system are safe.

Heath explains what a circuit breaker is, why they trip and how it protects a home. A circuit breaker is a device, installed in the electrical panel, that controls whether power can be sent from the panel through a circuit. Heath explains this ability is controlled by a switch that can be operated either manually—like when a person wants to interrupt power for service—or automatically, like a breaker trip.

He says power overloads, current “leaks”, and arcs are the three reasons that would cause a breaker to trip. A Power overload happens when a device is calling for more power than a receptacle , or a circuit is designed to provide. Current “leaks” are caused when current strays from the circuit for whatever reason, though it happens most commonly when moisture is present. Arcs can happen when the wire breaks down over time (due to overloads but also due to other factors, like animals chewing the wire and other decay) but what Heath sees the most is human error.

If a specific receptacle is consistently tripping the breaker, Heath advises to have a licensed electrician identify the problem to ensure the work is done safely.

What Happens When an Electrical Circuit Overloads

If you’ve ever plugged in one too many holiday lights, switched on a vacuum, or cranked up a space heater only to have the lights or appliance suddenly shut off, you’ve created an electrical circuit overload. The shutdown was triggered by the circuit’s breaker (or fuses ) in your home’s service panel. And while circuit breakers are reliable and do a good job preventing house fires due to overloads, the safest strategy is to manage your electricity usage to prevent overloads in the first place.

What Is an Electrical Circuit Overload?

An electrical circuit overload occurs when you draw more electricity than a circuit can safely handle.

How Do Electrical Circuit Overloads Work?

Electrical circuits are designed to handle a limited amount of electricity. Circuits are made up of wiring, a breaker (or a fuse, in old wiring systems), and devices (such as light fixtures, appliances, and anything plugged into an outlet). The electricity usage of each device (when running) adds to the total LOAD on the circuit. Exceeding the rated load for the circuit wiring causes the circuit breaker to trip, shutting off the power to the entire circuit.

If there were no breaker in the circuit, an overload would cause the circuit wiring to overheat, which could melt the wire insulation and lead to a fire. Different circuits have different load ratings so that some circuits can provide more electricity than others. Home electrical systems are designed around typical household usage, but there’s nothing to prevent us from plugging in too many devices on the same circuit. However, the more you know about the layout of your home’s circuits the more easily you can prevent overloads.

Signs of Overloaded Circuits

The most obvious sign of an electrical circuit overload is a breaker tripping and shutting off all the power. Other signs can be less noticeable:

• Dimming lights, especially if lights dim when you turn on appliances or more lights.
• Buzzing outlets or switches.
• Outlet or switch covers that are warm to the touch.
• Burning odors from outlets or switches.
• Scorched plugs or outlets.
• Power tools, appliances, or electronics that seem to lack sufficient power.

Buzzing sounds , burning smells, and unusually warm devices also can indicate other wiring problems, such as loose connections or short circuits . If any of these problems persist after you’ve taken steps to prevent circuit overloads, contact an electrician.

Mapping Your Home’s Circuits

The first step to preventing electrical circuit overload is to learn which circuits power which devices. When you’ve mapped the basic circuit layout, you can calculate the safe load rating of each circuit to get a sense of how many things you can operate on that circuit. For example, if your kitchen lights dim when you turn on your toaster oven (a power-hungry appliance), that tells you that the toaster and lights are on the same circuit (even though they shouldn’t be) and that you’re close to maxing out the circuit capacity. Mapping the circuits also can tell you if there’s a need for new circuits to meet the normal demands of the household.

Mapping circuits are simple (if repetitive): Get a notepad and a pencil. Open the door to your home’s service panel (breaker box) and turn off one of the breakers with the number 15 or 20 stamped on the end of the breaker switch. (Don’t bother with the breakers stamped with 30, 40, 50, or higher numbers; these are high-voltage circuits for appliances like electric ranges, water heaters, and clothes dryers, and you’re not plugging ordinary appliances into these circuits.) Note on the pad where the circuit lies in the panel so you can identify it later.

Next, walk through the house and try all the lights, ceiling fans, and plug-in appliances. Write down everything that doesn’t have power, and note the room it is in. Also, test each outlet with a voltage tester or receptacle tester, or even a plug-in light or lamp, recording all that don’t work. You don’t necessarily have to go through the entire house for each circuit. And if your electrician was thorough, there may be helpful labels next to the breakers, indicating the circuit areas (“Southeast bedroom,” “Garage lights,” etc.). But for accurate mapping, you should test each area broadly because circuits can have oddball members—a microwave on a hallway lighting circuit, for example.

After you’ve tested the circuit area, go back to the panel, turn on the first breaker, then turn off the next one in the row, and repeat the test. Repeat the process for all of the “15” and “20” circuits.

Calculating Circuit Loads

Your circuit map tells you which devices are powered by each circuit. Now you have to calculate how much power those devices are using. To do that, you need a quick lesson in electrical energy. Electricity is measured in watts; a 100-watt light bulb uses 100 watts of electricity. A watt is the product of voltage (volts) and amperage (amps):

1 volt x 1 amp = 1 watt

To calculate the total load on each circuit, add up the wattage of all the devices on that circuit. Light bulbs and many small appliances have labels noting their wattage. If a device gives you only amps, multiply the amp value by 120 (the voltage of standard circuits) to find the wattage. Include all devices that are permanently wired to the circuit as well as plug-in appliances that you don’t move very often (like a toaster oven, or a heater in a particularly cold room).

Compare the total wattage of each circuit to the load rating of that circuit. The circuits with “15” breakers are rated for 15 amps. The maximum load rating of one of these circuits is 1,800 watts:

120 volts x 15 amps = 1,800 watts

If you try using more than 1,800 watts on that circuit, you will overload it, and the breaker will trip.

The circuits with “20” breakers are rated for 20 amps and have a maximum load rating of 2,400 watts:

120 volts x 20 amps = 2,400 watts

Compare the wattage total (how much electricity you’re using) and the load rating for each circuit. For example, a 15-amp circuit serving lights and outlets in a living area might be providing power for 500 watts for lighting, 500 watts for the TV and cable box, and 200 watts for the sound system, for a total of 1,200 watts. If you plug in a 700-watt vacuum while the TV, stereo, and lights are on, you’ll exceed the 1,500-watt rating on the circuit breaker, causing it to trip and shut off the power.

The maximum load on each circuit isn’t the ideal target. For a margin of safety, it’s best if the normal load on a circuit does not exceed 80 percent of the maximum (rated) load. For a 15-amp circuit, the safe load target is 1,440 watts; for a 20-amp circuit, the safe load is 1,920 watts.

If your circuit calculations indicate that you’re drawing more wattage from a circuit than the safe load number—or you’re exceeding the rated load and frequently overloading the circuit—there are a few ways to reduce the load on the circuit to prevent overload:

• Move plug-in appliances to a circuit that is less-used (use your mapping and circuit calculations to identify circuits that have plenty of available wattages).
• Remember not to turn on too many things at once. For example, turn off the TV and sound system while you vacuum (you can’t hear them anyway).
• Reduce lighting loads by replacing incandescent or halogen light bulbs with energy-efficient LED (preferably) or CFL (fluorescent) bulbs.
• Install new circuits for high-demand devices. For example, if you run a lot of power tools in your garage workshop, but your garage is wired with all of the outlets and lights on the same 15-amp circuit, install a new 20-amp circuit supplying a few new outlets for your tools.

What Causes a Circuit Breaker to Trip?

Circuit breakers are an essential component of any home electrical system. They are designed to protect our homes and appliances from electrical overloads and short circuits. But what causes a circuit breaker to trip, and how can we prevent it from happening? In this comprehensive guide, we’ll delve into the common reasons why circuit breakers trip and provide some practical tips to avoid this problem.

A circuit breaker may trip due to three primary reasons: overloads, short circuits, and ground fault surges. Overloads occur when a circuit draws more power than it can handle, usually due to too many appliances operating on the same circuit. Short circuits and ground fault surges happen when a hot wire comes into contact with a neutral wire or a ground wire, causing a large amount of current to flow and overheat the circuit. Less common causes can include faulty wiring, a damaged breaker, or power surges from storms and lightning strikes.

Understanding Circuit Breakers

Before we dive into the reasons, it’s important to understand what a circuit breaker is and how it works. A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent, overload, or short circuit. Its primary function is to interrupt the current flow when it detects a fault in the electrical system, thereby protecting equipment and preventing the risk of fire.

Circuit breakers can be reset either manually or automatically to resume normal operation, unlike fuses which must be replaced after operating once. They come in various sizes, from small devices that protect low-current circuits or individual household appliances to large switchgear designed to protect high voltage circuits feeding an entire city.

Common Reasons for a Circuit Breaker to Trip

There are three primary reasons why a circuit breaker might trip:

• Overloads : This is the most common reason for a circuit breaker to trip. Overloads occur when a circuit is drawing more power than its rated capacity. This can happen when too many appliances or devices are operating on the same circuit at the same time.
• Short Circuits : A short circuit is a more serious issue. It occurs when a “hot” wire comes into contact with a neutral wire in one of your outlets. This can cause a large amount of current to flow, creating more heat than the circuit can handle, which in turn causes the circuit breaker to trip.
• Ground Fault Surges : Similar to a short circuit, a ground fault surge happens when a hot wire comes into contact with a ground wire or the metal box that houses the wiring. This causes a sudden rush of electricity that can heat up the circuit, causing the breaker to trip.

Other less common reasons for a circuit breaker to trip include faulty wiring, a damaged breaker, or power surges from storms and lightning strikes.

Preventing Circuit Breakers from Tripping

Here are some practical tips to prevent circuit breakers from tripping frequently:

• Distribute Electrical Devices : Avoid plugging too many devices into one circuit. Instead, distribute them across multiple circuits to balance the load.
• Inspect and Replace Old Wiring : Old and faulty wiring can cause short circuits or ground faults. Regular inspection and replacement of old wiring can prevent these issues.
• Use Surge Protectors : Surge protectors can protect your devices and prevent circuit breakers from tripping during power surges.
• Replace Old or Damaged Circuit Breakers : If your circuit breaker is old or damaged, it may trip more frequently. Consider replacing it with a new one.

In conclusion, circuit breakers play a vital role in maintaining the safety of our homes. Understanding why they trip and how to prevent it can help us maintain a safe and efficient electrical system. If your circuit breaker continues to trip frequently, it’s best to consult a professional electrician to diagnose and fix the problem. Remember, dealing with electricity can be dangerous, and it’s always better to be safe than sorry.

Frequently Asked Questions

What is the difference between a circuit breaker and a fuse.

Both circuit breakers and fuses serve the same purpose – to protect an electrical circuit from damage caused by an overcurrent, overload, or short circuit. The main difference is how they handle the fault condition. A fuse will melt when overloaded, interrupting the circuit but requiring replacement. On the other hand, a circuit breaker will simply trip (switch off) and can be reset either manually or automatically to resume normal operation.

How can I tell if my circuit breaker is faulty?

Common signs of a faulty circuit breaker include the breaker constantly tripping, the breaker not staying reset, a burning smell or visible burn marks around the breaker, or physical damage to the breaker itself. If you suspect your circuit breaker is faulty, it’s best to consult a professional electrician.

How often should circuit breakers be replaced?

There’s no hard and fast rule for when to replace a circuit breaker. They can last for many years, even decades, if they’re not exposed to excessive moisture or heat and are not constantly being tripped. However, if you’re experiencing frequent tripping or other issues, it’s a good idea to have them inspected by a professional electrician, who can recommend replacement if necessary.

Can I reset a tripped circuit breaker myself?

Yes, you can usually reset a tripped circuit breaker yourself. First, identify the tripped breaker in your electrical panel. It will typically be in the “off” position or in a middle position between “on” and “off.” Simply switch the breaker to the “off” position and then back to the “on” position. However, if the breaker continues to trip, it’s best to consult a professional electrician as it could be a sign of a more serious problem.

What Does a Circuit Breaker Tripping Mean?

 when there's a circuit breaker tripping, it can indicate that the circuit breaker detects an electrical issue, and it shouldn't be ignored..

The pandemic-induced surge in home electricity use is real. Consider that, according to the National Bureau of Economic Research, American spending on  home power consump tion  skyrocketed by $6 billion! 

With more usage comes more problems, and circuit breaker issues are among the most common. When there's a circuit breaker tripping, it can indicate that the circuit breaker detects an electrical issue, and it shouldn't be ignored.

 Circuit Breaker Tripping 101

Most circuit breaker issues center around circuit overload. Circuit breakers are a vital part of your home's electrical system since they are designed to prevent costly and damaging surges in electrical current. 

The breaker, working in tandem with a fuse, serves as an electrical unit's internal sensing mechanism. At the slightest sense of excess current, the circuit breaker will "trip," triggering a cease in all electrical activity within the circuit.

Not only can such a smart mechanism help with preventing damage to wires and other electrical components, but circuit breakers can also save lives by preventing electrical fires. According to the National Fire Protection Association,  electrical failures  were the second leading cause of home fires between 2012-2016.

So why do circuit breakers trip? Here are the three most common reasons for circuit breaker tripping and how you can go about fixing a circuit breaker.

 1) Circuit Overload

By far, the m ost common reason a circuit trips is because it's overloaded. Even running a circuit at its electrical capacity can cause home appliances to burn out or a circuit to trip. Ideally, you want to run a circuit below its capacity to keep it from tripping and to prevent any damage from occurring. 

The most familiar example of circuit overload is an over-stuffed power outlet. When you have a dozen gadgets all demanding electrical current to work, eventually that single outlet's capacity will experience overload, and the circuit will trip.

Knowing what each electrical outlet in your house can handle is key to preventing circuit overload. Even a single high-current appliance like a washing machine cannot plug into just any outlet.  Understanding your power outlets  is critical for a safer home.

Before you head to your circuit breaker box or call your electrician, notice what was plugged in at the outlet where the tripped circuit occurred. You may have overloaded it.

 2) Short Circuit

Similar to an overload, when a circuit "shorts," it responds to more current than it can bear. But a short circuit is far more dangerous. 

A short circuit occurs when a "hot" or active wire comes into contact with either another active wire or a neutral wire. The touching wires cause a spike in current that can likewise trip your circuit breaker. Most often, the causes for short circuits are mechanical issues like: 

• Loose Connections
• Improper Wiring
• Damaged Wires

Faulty components, like switches, plugs, cords, appliances, or lighting fixtures, are often culprits of short circuits. Short circuits can occur if you screw or nail into drywall and penetrate an electrical wire.

Remember that short circuits may involve faulty circuit wiring, but the device you're plugging in can cause the problem as well. Keep this in mind, especially if you're using older devices or gadgets that have been out of commission for years, as these can be more prone to short circuits, independent of what's going on in the outlet.

Due to their volatile nature, short circuits are some of the biggest causes of electrical fires, so be extra attentive and don't hesitate to call a professional. As a general rule, most people should never  DIY electrical issues  in their homes.

 3) Ground Fault Surge

 Ground fault surges are similar to short circuits because they involve a sudden spike in current, creating an overload. Ground faults occur when an active wire comes into contact with the ground wire. The contact can come directly or indirectly via the metal housing that connects to the ground wire. 

Copper grounding wires are especially prone to ground fault surges. Copper is the most  conductive material  in everyday use when it comes to home electrical systems. When a hot wire touches the ground wire's copper coating, it results in superconductivity that overwhelms the circuit. A similar result can come from an active wire touching a ground's metal outlet box. 

 Understanding and Fixing Circuit Breaker Issues

So how should you go about troubleshooting a circuit breaker issue? Even though you should leave anything remotely technical to a professional, there are a few things you can do to investigate circuit breaker trip meaning.

First thing's first. Make sure you and your family are safe. Check for signs of excess heat or burning—smell for what could be smoke from an electrical fire. If you sense any signs of a fire, evacuate and call 911.

Check for any discoloration around an outlet. Also, make a note of any sparks or popping noises coming from the outlet. Any of these could be a sign of a ground fault surge or a short, in which case simply flipping the circuit breaker switch won't help. And remember, the older the outlet, the more likely it is to experience problems.

Look for any signs of damage to your devices. Remember that the problem could be coming, not from your home's outlet, but from what you plugged in.

If there are no signs of a blown circuit, try going to your circuit breaker service panel. You may be familiar with this metal box, often located in a garage or utility room. Flip the switch of the house area that tripped, and see if that "resets" the circuit. 

 Fixing a Circuit Breaker

If a simple flipping of the switch doesn't work, it's time to call a professional electrician. The seasoned team at Buell Electric can assess the problem and fix a circuit breaker, which may involve repairs or upgrades. 

Circuit breaker tripping may be as innocent as overloading an outlet, but it can point to more serious problems as well. The best way to know for sure is to  contact us  today.

Does Your Circuit Breaker Keep Tripping? Here’s How to Find the Cause

Last Updated: May 6, 2023 Fact Checked

Common Causes of Tripped Circuits

Finding overloaded circuits, finding short circuits, finding ground faults.

Picture this: you’re watching TV or browsing on your phone when, suddenly, half the lights in your home turn off. You check your circuit breaker and flip one of the switches back to “ON,” but an hour later it trips again…and again. Sound familiar? Having your circuit breaker trip over and over can be frustrating, but don’t sweat. In this article, we’ll explain the most common causes of a tripped circuit breaker. Keep reading to learn which causes might apply to your situation, when to try do-it-yourself fixes, and when it’s best to call an electrician.

Things You Should Know

• The most common causes of tripped circuit breakers are overloaded circuits, short circuits, and ground faults.
• Test for overloaded circuits by resetting your breaker and plugging in devices until it trips again. The device that caused the trip is overloading the circuit.
• Test for short circuits by resetting your breaker and plugging in items into different sockets. The device or socket that always trips the breaker likely has a short circuit.
• Have an electrician test for ground faults if you’ve already ruled out overloaded and short circuits. Ground faults are too dangerous to test for on your own.

• For example, if your bathroom and kitchen are part of the same circuit—that is, the plugs in your kitchen and bathroom are all connected to the same switch on your circuit breaker—then the breaker might trip if you run your microwave and hair dryer at the same time.

• Short circuits often happen when wires come loose or get damaged by corrosion or wear and tear, or even from an animal chewing through them. [3] X Research source
• Short circuits can occur in the wiring in your home or in individual devices. For instance, a refrigerator can have a short circuit due to a loose wire.

• Ground faults often happen due to water leaking into outlets or devices. They also occur when loose or corroded wires come into contact with ground wires, or when defective devices cause electricity to flow to a ground wire.

• If you have multiple devices sharing a single outlet in the area affected by the tripped breaker, it’s likely that that group of devices is causing the overload. [6] X Research source

• Wear safety goggles or stand to the side of a breaker when flipping a switch to “ON” in case of sparks.
• If the switches aren’t labeled, narrow down the affected area by flipping the switch to “ON” and checking which devices and lights turn on again.
• If multiple switches tripped at the same time, there might be an overloaded circuit in more than one area of your home, or you may have another issue such as a short circuit or ground fault.

• If none of the devices immediately trip the circuit breaker, it’s possible that your circuit isn’t getting overloaded right away. Leave the devices plugged in and turned on for a few minutes to see if the breaker trips again.
• If the breaker trips after several minutes, try the process again, but leave 1-2 less important devices unplugged. Eventually, you’ll find a combination of devices that doesn’t trip the circuit breaker.

• Leave your devices plugged in and on for a few hours. If the circuits are not overloaded, the circuit breaker shouldn’t trip.
• If the circuit breaker trips for the same part of your home again, plug additional devices into other outlets. You may need to try different combinations of plugs and outlets to see which combination doesn’t overload your circuits.
• If you try several combinations and the breaker continues to trip, it’s possible that you have a short circuit or ground fault somewhere in your home.

• If devices are plugged into surge protectors, unplug each device from the surge protector before unplugging the surge protector itself.

• If the circuit breaker trips whenever you plug something into a particular outlet, you probably have a short circuit in that outlet.
• If one particular device always trips the breaker, but other devices don’t, you probably have a short circuit in that particular device.

• If the device you want to test is too large to move—such as a kitchen refrigerator or washing machine—use a long extension cord to reach other outlets.

• If you find a short circuit in an individual device, check if your product is covered by a warranty. If it is covered, you might be able to get it fixed or replaced for free.

• Tell your electrician which outlet or area of your home is affected by the tripped circuit breaker. This will help them narrow down the exact problem.
• Avoid using sockets that appear water-logged or that show signs of water damage.

It’s one of the most annoying, not to mention potentially dangerous issues for a homeowner- a tripping circuit breaker. If you’re not an electrician, diagnosing what caused the trip can be overwhelming and cause even more harm to your home and appliances.

Right Electrical Services wants to make this common but frustrating experience easier for you to handle! We have compiled a list of 4 common reasons your breaker may short circuit and how to fix the issue! Read on and do not hesitate to call us for your circuit breaker needs and issues ! We’ll be happy to help!

How Does a Circuit Breaker Work?

To start, let’s talk a little bit about how circuit breakers work and what their importance is. Each home’s electrical panel is filled with multiple breakers. These circuit breakers service electricity to different parts of your home and feed off of one “main circuit breaker”. The main circuit breaker is not much different than the other breakers occupying your electrical panel. However, it has the ability to handle larger amounts of amperage. It’s very important to know exactly how many amps your home is rated for and this can vary depending on your home’s age. We’ll get more into that later.

As annoying as it may be, circuit breakers trip for a very important reason. Circuit breakers are designed to completely shut off power to your home in the event that the demanded load of energy grows too high. Sometimes the issue occurs due to serious issues within the electrical system. While we may groan and complain when this happens, it’s important not to take this event lightly. While a circuit breaker can trip usually causing nothing more than a momentary power surge, this is not always the case. Sometimes there are much more serious problems that need to be diagnosed. In the case of a main circuit breaker trip, there are more questions you should be asking. Main circuit breaker trips are more rare because individual circuit breakers are designed to prevent this in the first place.

1. A Circuit Breaker Overload

The most common cause of circuit breaker issues are typically due to an overload. This is an extremely easy mistake to make. When running too many appliances all at once, your breaker can overload and cause a trip. Trips are even more common in the case of appliances that consume large amounts of power. Remember earlier when we mentioned that the amount of amps your home is rated for was important? This is where that comes in.

Often, older homes are not equipped to handle the ever-increasing electrical demands of today. According to the Jackson Electric Membership Corporation, overloaded circuits are the cause of more than 40,000 residential fires each year. Each circuit in a home’s electrical panel are designed to only handle a certain amount of wattage and going over this limit causes an overload. Appliances that create heat such as hair dryers and heaters can draw up to a whopping 1,800 watts on their own! Considering many residential homes are equipped with a branch of circuits possessing around 15-20 amps and only capable of handling up to 1,900 watts before tripping, you can see the concern.

The Solution

So what can you do to prevent a circuit breaker overload? There are a couple of solutions that we can recommend:

Attempt to redistribute especially power-heavy appliances to a general purpose circuit. In order to figure out if this is a good option for you, you can start by adding up all of the electrical loads on a circuit. You can then refer to the National Electrical Code and determine whether or not it exceeds their limit. In the case that it does, it’s a good idea to redistribute your appliances. Right Electrical Services can help you with this! Call us today to explore your options in redistributing your appliances to a general purpose circuit ! Turn off appliances that don’t have to be in use. Try to designate and decide when you run your especially power-heavy appliances. Switching off non-essential appliances when not in use can save the extra stress on your circuit breakers big time!

2. Short Circuits

Short circuits are among one of the most dangerous reasons for a circuit breaker trip. A short circuit occurs when a hot wire (black wire) touches another hot wire or touches a neutral wire (these are typically white). Two of these wires touching within an outlet can cause current flows that end up creating more heat than a circuit is designed to handle. This causes a shut off. Short circuits are especially dangerous because the large amounts of heat produced can cause fires within your wall cavity! Yikes!

Short circuits can be identified by the smell of burning and black/brown discoloration around the outlet. If you notice this in your home, don’t delay! Short circuits are a very serious issue that you cannot ignore. Thankfully, a licensed electrician can easily identify the cause of the issue and help you keep your home safe. While wires can cross for multiple reasons, it is sometimes as simple as a loose connection or faulty wiring.

For more tips on making sure your outlets are properly upgraded and functioning at their best, you can check out our blog post on electrical outlet upgrades!

3. Ground Fault

Ground faults are pretty similar to short circuits. The same dangers occur in the case of a ground fault as with a short circuit. With a ground fault, a hot wire actually crosses and interacts with the ground wire (bare copper) within the outlet.

Like a short circuit, a ground fault can be identified by the tell-tale signs of the issue. The smell of burning and discoloration of the outlet can also occur here. However, there are a few different causes of a ground fault that you should be aware of.

Leakage of water into an electrical box can end up causing a ground fault because water is a conductor of electricity. A GFCI outlet is designed to cut off the flow of current in the case of a ground fault. If your GFCI outlet is faulty or malfunctioning, it may neglect to do so. In order to prevent this issue, it is important to make sure your GFCI outlet is functioning properly.

4. Appliances

There are many appliances common for causing a circuit break to trip. Unfortunately, these appliances are frequently used and necessary to living our day to day lives. These appliances include:

Irons – Clothes irons obviously heat up very quickly. Many of us don’t take into consideration that outlets in each room of our house are designed to handle a certain amount of energy. Where do you tend to find yourself ironing your clothes most often? If you said your bedroom or living room, you are not alone. Outlets in bedrooms and living rooms are typically not equipped to handle as much energy as those in, say, our kitchens. Due to this, running an iron on the highest setting for a long period of time or forgetting to switch it off when you’re done can cause a breaker trip.

Hair Dryers – Here is another pesky appliance that we all use on a daily basis. Similarly to a clothes iron, these devices generate a ton of heat within an incredibly short period of time.

Fans – Ever found yourself scrambling to turn on every fan in your home in the midst of a particularly hot summer? Of course you have! Unfortunately, running multiple fans in your home at the same time can cause a circuit breaker trip. Ceiling fans use a significant amount of power and running them all day, especially, can cause too much stress on your breaker.

Older Household Appliances – Appliances that are on the older side tend to be the most power-hungry of them all. Let’s take older refrigerators for example. Refrigerators tend to last for a long time, decades even- but this can come at a cost. Although reliable, older refrigerators tend to demand a lot of energy and can end up causing a circuit break when the temperature rises in your home in the summer. In this case of older appliances, “If it’s not broke, don’t fix it” is not always the best motto to live by.

In the case of older appliances, the solution is actually pretty simple- keep up to date on upgrades and repairs! You should also limit your appliance use as much as possible! If you suspect one of your more power-hungry appliances could be the culprit to your frequent breaker trips, look into repairs and upgrades to less needy models. In the case of things like clothes irons, hair dryers, and ceiling fans you should limit your use as much as possible. With a little self-discipline, you can really reduce the risk of a circuit breaker trip in your home.

Breaker Keeps Tripping: Understanding the Common Causes and Solutions

When a circuit breaker trips, it protects your device and circuit; it’s just doing its job unless it is damaged.

Do you notice that sometimes the lights of a residential place go off due to circuit breaker tripping, or sometimes the fuse blows up? It is due to some faults in the electrical network. I see these faults too much because I work as an electrical maintenance engineer.

I will discuss different reasons that cause circuit breaker tripping. I won’t rely only on my long work experience as an engineer, which is now about 15 years, but also I will provide you with the results of deep searching about circuit breaker tripping.

Table of Contents

How To Find The Reason Behind Tripping My Circuit Breaker?

Tripping of a circuit breaker can occur due to various reasons, such as overloading, short circuits, ground faults, or issues with the electrical appliances or wiring. Here are some steps to help you identify the reason behind the tripping:

Identify the Circuit: Determine which circuit breaker has tripped and which area of the house or building is affected. This can help narrow down the potential causes.

Unplug Appliances: If the tripping occurs when a specific appliance is used, unplug that appliance and try resetting the circuit breaker. If the breaker does not trip, the appliance might be faulty and cause an overload.

Check for Overloading: Assess whether the circuit is overloaded by connecting too many high-powered devices to the same circuit. Try redistributing the load by connecting devices to different circuits.

Inspect for Short Circuits: Examine the electrical outlets, switches, and wiring for signs of damage or exposed wires that could be causing a short circuit. If you notice any issues, consult a qualified electrician to repair or replace the affected components.

Look for Ground Faults: Ground faults occur when a hot wire comes into contact with a ground wire or a metal wall box. Use a ground fault circuit interrupter (GFCI) tester to identify any potential ground fault issues and address them accordingly.

Check for Wet Conditions: If the circuit is in a damp or wet area, it could lead to a ground fault. Ensure that all electrical components in such areas are moisture-resistant and properly grounded.

Inspect the Breaker Itself: Examine the circuit breaker for any signs of damage, corrosion, or overheating. If you notice any issues, consider replacing the circuit breaker with a new one.

Consult a Professional Electrician: If you are unable to identify the cause of the tripping or if you suspect a more complex electrical issue, it is advisable to consult a licensed electrician. They can conduct a comprehensive inspection of the electrical system and troubleshoot any underlying problems.

It is crucial to prioritize safety when dealing with electrical issues. If you are unsure about how to proceed or are not comfortable handling electrical components, it is best to seek professional assistance to ensure a safe and effective resolution to the problem.

What would cause a circuit breaker to keep tripping?

Now, after this quick discussion for non-technical persons. let’s move to the electrical engineering discussion.

Overloaded Circuit:

One of the main reasons for circuit breaker tripping is the overloaded circuit in the electrical system. When many loads are connected to the circuit, the circuit attempts to draw a greater electrical load than its rated value. Due to this, the circuit breaker heats up, and the breaker tripping occurs.

Electrical Short Circuit:

Another reason for the breaker tripping is the electrical short circuit. A short circuit occurs due to low insulation resistance .

When the positive and negative (live and neutral) terminal connects with each other in the absence of any resistance. This causes an unimpeded flow of electricity. A large amount of current flows through a breaker that causes tripping.

It is worth mentioning here how to decide whether the tripping occurs due to a short circuit . The answer is clear and simple. If a circuit breaker trips instantly again and again after you reset it, the tripping occurs due to a short circuit.

How Do I Know That I Have a Short Circuit at the House? If you find fuses being blown regularly or a circuit breaker tripping frequently, it might be a symptom of a short circuit.

A fuse will usually explode, or a circuit breaker will trip instantly. If a new fuse with the proper rating also blows, you’ve got a short circuit.

If a circuit breaker is reset and it trips again instantly, as you connect it, you have a short circuit or a broken circuit breaker. Read my detailed article about Electrical short circuits, why is it dangerous?

Ground Fault:

Another reason that causes the circuit breaker tripping is the ground fault. A ground fault is a type of short circuit when a hot wire comes in contact with the ground or any other type of metal.

The ground fault causes an increase in the flow of current. It causes the circuit breaker to heat up and as a result, circuit breaker tripping occurs.

Some ground faults are not detectable by normal MCB. So it’s recommended to use GFCI (ground fault circuit interrupter) This is better for human safety as this breaker can detect small milli-amperes and trips before a shock happens. Read my article on my other site: Surge Protectors and GFCI Outlets: Can They Safely Coexist?

When fluctuation or sparking occurs between two-wire connections at a point. Arc faults occur.

Sometimes the screws at a point become loose, In this case, AFCI (arc fault circuit interrupter) is recommended.

While the circuit breaker is an Arc fault interpreter (AFCI ). It detects the early wiring problem and trips in advance to stop the flow of a large amount of current.

Bad Circuit Breaker:

Sometimes the circuit and loads are all OK and in good condition. But the breaker keeps tripping randomly.

This is a sign that the circuit breaker is bad. Like any device, breakers have a lifetime, and then breakers go bad . And it’s time to replace it.

The circuit breaker keeps tripping immediately

If your circuit breaker keeps tripping immediately after resetting it, this indicates a severe electrical issue that requires prompt attention. Here are some steps to follow to address the problem:

Identify the Problem Circuit: Determine which specific circuit is causing the repeated tripping. This can help pinpoint the area of concern and focus your troubleshooting efforts.

Disconnect All Appliances: Unplug or disconnect all devices and appliances from the circuit that keeps tripping the breaker. If the breaker doesn’t trip after disconnection, the issue may be related to one of the appliances or devices.

Check for Short Circuits or Ground Faults: Inspect the wiring, outlets, and switches for signs of damage, exposed wires, or any moisture intrusion. Focus on the affected circuit and look for any visible signs that might indicate a short circuit or ground fault.

Examine the Breaker Itself: Check the circuit breaker for any signs of damage, overheating, or wear. A faulty breaker could be the root cause of the repeated tripping. Consider replacing the circuit breaker with a new one if it appears damaged.

Consult a Professional Electrician: If you are unable to identify the cause of the immediate tripping, or if the issue persists despite your troubleshooting efforts, it is essential to seek assistance from a qualified electrician. They can perform a comprehensive inspection of the electrical system and troubleshoot the problem effectively.

It is crucial to prioritize safety when dealing with electrical issues. If you are uncertain about how to proceed or are uncomfortable handling electrical components, it is best to seek professional help.

Electrical problems can be complex and potentially dangerous, so it is important to have them addressed by a licensed electrician to ensure the safety of your property and its occupants.

Can a circuit breaker trip for no reason?

A breaker will trip for no reason if it malfunctions . A breaker will trip when a short circuit occurs on an electrical circuit, causing sparks, popping sounds, or smoke to be produced.

A loose connection, slipping wire, or even damage from animals chewing on cables could cause this.

If you didn’t find any faults like a short circuit , overload, or lost connection, your circuit breaker might be old and unable to carry current anymore.

In other words, it has become bad. It would be best if you replaced it for the circuit to continue operating.

Why is the circuit breaker tripping without load?

If your circuit breaker trips without loads, a wire with damaged insulation somewhere in the electrical panel or in power outlets can be the cause of breaker tripping and will continue to do so until you fix it .

A general wiring issue can potentially be the reason why a circuit breaker trips. You can have obsolete wiring if your home is older.

The issue with older electrical systems is that new technology and appliances frequently demand more power than previous systems can safely handle.

The older wiring can’t keep up with the increasing demands as our daily energy needs increase. This may be the problem if several breakers are often tripping without a load. Otherwise, there can be a problem with the breaker panel itself.

When your breaker trips without any load being present, you should take into consideration the following three wiring problems:

Current Leakage: One possibility is that one or more of the input wires have current leakage, which causes the circuit breaker to trip even when there isn’t a load attached to it. If so, your annoying issue is taking place for your own benefit. tripping is a precaution for the safety of your all-electrical devices.

Damaged Wires : Not simply the input cables might be damaged; it could happen everywhere. They could have been accessed by pests or insects that, only by gnawing, caused significant harm. This kind of issue may be sufficient to trigger a breaker trip even with no loads.

A Loose Wire in an Outlet : This loose wiring issue may be pretty frustrating. In other words, a loose wire in one of your outlets will keep your breaker continuously tripping. If you have a GFCI outlet, this is a very typical issue (Ground-Fault Circuit Interrupter).

Why shouldn’t you reset a tripped circuit breaker immediately?

The straightforward answer is that you shouldn’t reset a circuit breaker unless you are sure of the reason for the fault and that it poses no danger.

Note that if you reset it immediately it may trip again in case it is still hot, even if the fault is cleared.

Circuit breakers are there to safeguard your family, your house, and yourself. When a circuit breaker trips, it indicates that a current greater than the trip current is passing through it.

In case of a faulty circuit or wires, or a short circuit, the circuit breaker will trip again immediately if you reset it.

The short circuit current makes the circuit breaker get hot and trip, it should be cooled before you reset it.

Can a tripped breaker stop a fire?

Yes, if tripping happen before the fire catch wires or panel. But it won’t if tripping happens after the fire catch wires or panel .

There can be two scenarios, 1 st one is before the wiring or breaker panel catches fire.

And 2 nd is the role of the circuit breaker after catching fire let’s explore both scenarios in detail below:

Role of circuit breaker before Catch Fire :

Tripped circuit breakers can prevent fire and protect electrical systems against overloads and short circuits, circuit breakers assure electrical safety in homes, offices, and other buildings as well as for industrial uses.

The circuit breaker instantly shuts off the electrical circuit when a problem is found, protecting the wires and reducing the chance of catching fire.

Role of circuit breaker after catching fire:

Tripped circuit breakers didn’t play any role and could not provide safety to the system after catching fire.

If the circuit breaker is not tripped due to any reason or sometimes the fault current is too much bigger than the rating of the cable, then the circuit breaker wiring or panel box catches fire.

Can tripping circuit breaker damage your devices?

Tripping circuit breakers themselves do not typically cause direct damage to your electrical devices.

In fact, the primary purpose of a circuit breaker is to protect your devices and electrical system from potential damage due to electrical overloads or short circuits.

When a circuit is overloaded or a short circuit occurs, the circuit breaker is designed to trip and cut off the flow of electricity, preventing excessive current from damaging your devices and wiring.

However, frequent or repetitive tripping of circuit breakers may indicate underlying issues within the electrical system that could potentially affect connected devices. Repeated tripping may point to problems such as overloading, short circuits, ground faults, or other electrical faults that could impact the functionality and safety of your devices.

Indirectly, sudden loss of power due to a tripped circuit breaker can cause data loss or corruption in electronic devices like computers, especially if they are not connected to an uninterruptible power supply (UPS). Additionally, frequent power fluctuations resulting from faulty electrical systems can gradually wear down sensitive electronic components, reducing the lifespan of your devices over time.

To prevent potential damage to your devices, it’s important to address any electrical issues promptly. If you notice persistent circuit breaker trips, it’s advisable to consult a qualified electrician to identify the underlying cause and ensure that your electrical system is functioning safely and efficiently. Taking proactive steps to maintain your electrical system can help prevent potential damage to your devices and ensure the safety of your property.

Why is the Main circuit breaker tripping?

The main breaker can trip for a variety of reasons. Whether it be a lightning strike, a power surge from the utility company, or an overload to the electrical panel, the main breaker can be tripped due to any of these factors.

Furthermore, the main circuit breakers can trip simply because they’re worn out . There might be a situation when a branch circuit breaker fails and is no longer capable of tripping as designed, which may result in the main breaker tripping to provide secondary safety shutoffs in the event that the individual circuit breaker fails. 

Furthermore, If the total load demand becomes too much or if there is any significant issue with the electrical system, the main breaker cuts off electricity to the entire house.

These issues often entail brief power spikes, although it may be necessary to detect system issues occasionally.

The main circuit breaker “tripping” is somewhat uncommon since often, individual circuit breakers trip long before the main breaker has to shut down.

Does weather affect the circuit breaker?

Yes, weather affects the circuit breakers . In response to the heat generated by the circuit breaker, the bimetallic strip inside the breaker flexes and trips the breaker.

The hot weather also can cause a breaker to trip, it all depends on the thermal effect of heat that causes the bimetallic strip inside the breaker to flex and trip it.

On the other hand, as compared to hot weather, cold weather didn’t affect the circuit breaker as much as lead to tripping, but if there is a foggy season and too much moisture in the environment, that can cause tripping the breaker.

A breaker’s components can also be adversely affected by the ambient heat in the air surrounding the breaker. A circuit breaker should typically not be heated over 140°F. If it happens, it indicates a potential trip of the circuit breaker.

If you can’t keep your finger on the plastic portion of the circuit breaker without being burnt, it’s too hot, according to a reliable “rule of thumb.”

Why do my breakers trip when it rains?

The main cause of a breaker’s trip after the storm is a short circuit brought on by water .

Due to heavy rain, the electrical wire isolation may deteriorate after water exposure, causing a short circuit. Improper panel box installation might be another reason your circuit breaker tripped during the storm.

Rainwater may get into your circuit in a number of ways if the main line is not installed properly.

Water may enter your wiring conduits through the wire leading to the meter and electrical circuit. It’s also conceivable that the conduit or hose you used to install your main line will let water through.

Because of this, if the breaker box is in the basement, water may wet your circuit. The worst possible scenario for your house is a wet circuit breaker.

A wet circuit is dangerous because you might get electrocuted in addition to the electrical problems it can create.

Can you reset a breaker in the rain?

It is generally not recommended to reset a circuit breaker while it is raining or in wet conditions . Water can significantly increase the risk of electrical hazards, potentially leading to electric shocks or other safety risks.

Resetting a circuit breaker in the rain could expose you to electrical currents and pose a danger to your safety.

To ensure your safety when dealing with electrical components, including circuit breakers, it’s crucial to follow these guidelines:

• Safety First: Prioritize your safety at all times. Do not attempt to handle electrical components in wet conditions or when you are standing on a wet surface.
• Turn Off the Main Power: If you need to access the circuit breaker panel during wet conditions, make sure to turn off the main power to the house or the affected circuit before attempting any reset.
• Wait for Dry Conditions: If the circuit breaker trips during the rain, it is advisable to wait until the weather improves and the area is dry before attempting to reset it.
• Take Precautionary Measures: If you must work on electrical components in damp conditions, wear appropriate personal protective equipment (PPE) such as rubber gloves, rubber-soled shoes, and other safety gear to minimize the risk of electrical shock.

If you are unsure about how to safely handle a circuit breaker or if you are uncomfortable with electrical work, it is best to seek assistance from a qualified electrician.

Professional electricians have the necessary expertise and equipment to handle electrical components safely, even in adverse weather conditions.

Prioritizing safety is essential to prevent accidents and ensure the protection of both you and your property.

Can a storm and lightning cause a CB to trip?

Yes, storms and lightning can potentially cause a circuit breaker to trip. Lightning strikes can induce power surges in electrical systems, leading to a sudden increase in electrical current that exceeds the circuit breaker’s capacity.

In response to the excessive current, the circuit breaker will trip, cutting off the power supply to the affected circuit or the entire house to prevent electrical damage or fire hazards.

Additionally, storms can cause power fluctuations and electrical disturbances, which might impact the stability of the electrical supply. These fluctuations can result in overloading or short circuits within the electrical system, leading to the tripping of the circuit breakers.

To protect your electrical system during storms and lightning, consider taking the following precautions:

• Install Surge Protectors: Use surge protectors to safeguard sensitive electronic devices from power surges caused by lightning strikes or other electrical disturbances.
• Unplug Electronic Devices: Unplug sensitive electronic devices during thunderstorms to prevent potential damage from power surges or lightning strikes.
• Invest in Lightning Protection Systems: Consider installing lightning protection systems, such as lightning rods and surge arresters, to divert lightning strikes away from your property and protect your electrical system.
• Maintain the Electrical System: Regularly inspect and maintain your electrical system to ensure that it is in good condition and capable of withstanding electrical disturbances caused by storms and lightning.

If you experience frequent circuit breaker trips during storms or if you suspect damage to your electrical system as a result of a lightning strike, it is advisable to seek the assistance of a licensed electrician.

A professional electrician can assess the condition of your electrical system, identify any potential issues, and implement necessary measures to safeguard your property from electrical hazards.

Will a breaker trip if wires touch each other?

Yes, a circuit breaker can trip if wires touch each other, especially if the wires create a short circuit.

When wires make direct contact or create a path with low resistance between the hot and neutral wires or between the hot wire and the ground, a short circuit occurs.

This causes a sudden increase in electrical current, exceeding the circuit breaker’s capacity and triggering it to trip.

The purpose of a circuit breaker is to protect the electrical system and connected devices from potential damage caused by overcurrent situations like short circuits. When the circuit breaker trips due to a short circuit, it interrupts the flow of electricity and prevents further damage to the wiring, appliances, and other electrical components.

To prevent wires from touching and causing a short circuit, it’s essential to follow proper wiring practices, including:

• Using appropriate wire connectors and junction boxes to secure and protect wire connections.
• Insulating exposed wires to prevent contact with other wires or conductive materials.
• Maintaining proper wire spacing and organization to minimize the risk of accidental contact.

If you suspect that wires are touching or if you experience frequent circuit breaker trips, it’s essential to consult a licensed electrician to inspect your electrical system.

A professional electrician can identify any potential wiring issues, troubleshoot the cause of the tripping, and ensure the safety and functionality of your electrical system.

Can the circuit breaker trip if you hold it?

The circuit breaker standard UL489 requires circuit breakers to be “trip free”. A trip-free circuit breaker will still trip if you hold it in the ON position.

Yes, you can hold the toggle up, but that does not stop the breaker from tripping under an over-current condition.

A circuit breaker cannot be forced if it trips repeatedly; it will keep opening and burn out.

It is usually not harmful to have a momentary connection, as it will only last for a short time.

You will need to resolve the problem causing the trip and then you will need to replace the circuit breaker if it went bad.

Why is the circuit breaker not tripping?

The circuit breaker may not trip if it malfunctions due to (an entirely mechanical problem, or sustains partial or total damage ) Occasionally, a circuit breaker will not trip in circumstances of fault like a short circuit, or overload, indicating it is bad and must be replaced.

It is also possible for the cause of the problem to be entirely mechanical, which means there may be a physical switch that is stuck in the “on” position.

The circuit breaker may also malfunction without tripping if it sustains partial or total damage. On occasion, a power failure occurs as internal components melt. To ensure appropriate operation, examine the circuit breaker and replace the broken one.

Signs of damaged/ faulty circuit

• Inspect the circuit breakers for any burning odors.
• If the panel feels hot to the touch, the circuit is either broken or overloaded.
• If the circuit is beyond its prime or is too old, replace it with a new one.
• Parts become melted or scorched due to heat.
• The item is defective if it trips off more frequently while gadgets draw more power.

What happens if a breaker doesn’t trip in faults condition?

If a circuit breaker fails to trip during a fault condition, it can lead to various hazardous situations, including:

• Overheating and Fire Risk: When a circuit experiences an overload or short circuit, excessive current flows through the wires, leading to overheating. If the circuit breaker does not trip to interrupt the flow of current, the wires, insulation, or other electrical components can overheat and potentially ignite a fire.
• Equipment Damage: The excessive current in the circuit can damage connected electrical devices, appliances, and other equipment. Without the protection of the circuit breaker, the electrical components can sustain irreparable damage, leading to costly repairs or replacements.
• Electrocution and Safety Hazards: In the absence of circuit protection, the risk of electric shock or electrocution increases, especially if someone comes into contact with live wires or faulty electrical equipment.
• Damage to the Electrical System: Continual overloading or short circuits without interruption from the circuit breaker can cause significant damage to the overall electrical system, including the wiring, panels, and other connected components. This can lead to extensive repairs and pose a safety risk to the property.

To mitigate the risks associated with a circuit breaker failing to trip during a fault condition, it is crucial to regularly inspect and maintain the electrical system. Consider the following measures:

• Schedule Regular Inspections: Arrange for periodic inspections of the electrical system by a qualified electrician to ensure that the circuit breakers are functioning correctly.
• Test the Circuit Breakers: Conduct routine tests on the circuit breakers to verify that they trip appropriately during overload or short circuit situations.
• Upgrade to Advanced Protection: Consider installing advanced protection devices, such as ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs), to enhance the safety and reliability of the electrical system.

Prioritizing regular maintenance and promptly addressing any issues with the circuit breakers or the electrical system can help prevent hazardous situations and ensure the safety and functionality of your property.

Is the circuit breaker tripping a good or bad thing?

Yes, circuit breaker tripping is good from the perspective of the safety of your home and home appliances .

It also provides protection against dangerous electrical fire hazards due to short circuits and overloading as long as it is not a bad CB .

But sometimes, apparently, you didn’t see any issue, but your circuit breaker keeps tripping and can get you in trouble.

It can be due to wiring issues like too much old wiring, damaged cables, or loose cable connection, which is difficult to troubleshoot because you have to check all the outlet’s wiring connected to the breaker.

That can be time-consuming, but it’s necessary to troubleshoot the fault and rectify it as soon as possible to avoid any bigger damage or loss.

6 Reasons Your Circuit Breaker Keeps Tripping

Circuit breakers are indispensable components of your electrical system. The device will shut off when it detects a short circuit, an overload, or a power surge. It is common for the breaker to trip once in a while, but if it keeps tripping, it could be due to one of the the following issues.

1. Your Electrical System Has a Short Circuit

One common reason your circuit breaker keeps tripping is a short circuit. The simplest definition of a short circuit is contact between the neutral and the live wires. When the wires touch, it can cause your circuit breaker to trip immediately after turning it on.

Contact between the live and neutral wires will cause a sudden flow in current. The wires can overheat and may start a fire. A discolored receptacle or a burning smell are symptoms of a fault in the circuit.

The short circuit could also be in the appliance rather than the electrical system. You can identify the source of the problem by turning off all the electronics on the circuit. Switch them on one at a time until you find the appliance tripping the breaker.

It is advisable to remove the appliance or have an electrician troubleshoot the circuit. You could cause further damage to your equipment or risk electrocution. Consider consulting our electricians at Huft Home Services in Sacramento for prompt electrical service.

2. The Circuit Is Overloaded

Circuit overloading occurs when an electrical load exceeds the rating of your electrical system. The breaker will trip when it detects a current greater than the circuit’s rated value. Without the breaker, the wires will overheat and start a fire.

Burning smells, warm receptacles, or discoloration on switches could be signs of a circuit overload. You may notice lights dimming when you turn on an appliance. It means the circuit has insufficient amperage to power your equipment.

For example, if the lights flicker when you turn on the microwave, the circuit will need an upgrade. Also, connecting multiple devices could exceed the amperage of the electrical system. You could move some of the devices to another outlet.

You can also reduce the circuit’s load by using LED bulbs rather than incandescent ones. Avoid using extension cords excessively. A better long-term solution is to upgrade the electrical system to suit your lifestyle and energy needs.

You may need a 20-amp circuit in your workshop for your power tools. An aging vacuum cleaner or oven may draw more power from your electrical system as it becomes inefficient. If you are unsure of the cause of the problem, reach out to our electrical team.

3. Power Surges and Arc Faults

A power surge is a sudden spike in voltage. The voltage can vary from a minor increase to a considerable voltage spike that can damage appliances and valuable equipment. Even small increases can cause your electronics to fail gradually over time.

Sometimes lightning may cause a surge in your electrical system. A direct strike on the power line will trigger a voltage spike.

A power surge can also occur after an outage. When the electricity is restored, there is a jolt in the voltage. You can unplug all devices during severe storms to eliminate the risk of equipment failure.

The best way to protect your electronics is to use a surge protector. Many point-of-use surge protectors resemble extension cords, but it is worth noting not all extension cords are surge protectors.

A point-of-use surge protector is affordable and suited for powering one or two appliances. However, you could opt for a whole-house surge protector. A whole-house surge protector will keep your electrical system safe regardless of the source of the voltage spike.

4. Ground Faults and Electrocution Hazards

A ground fault is when the current takes an unintended path to the ground. It occurs when the live wire touches the appliance’s outer casing or ground wire. Electricians consider ground faults to be another type of short circuit since there is a bypass across the wiring.

As with short circuits, ground faults will reduce the resistance in the conductor. A lower resistance can allow the uncontrolled flow of current. Your circuit breaker will repeatedly trip if there is a ground fault in your electrical system.

The principal risk of a ground fault is an electrocution hazard. Touching an exposed wire can create a path of least resistance to the ground. Damp conditions can increase the risk of a ground fault and electrocution.

The NEC (National Electrical Code) requires GFCI (Ground Fault Circuit Interrupter) outlets in the kitchen, bathroom, or outdoors. A GFCI outlet constantly monitors the voltage in the hot and neutral wires. When there is contact between the hot and ground wire, the device stops the current.

A ground fault could also occur due to wiring faults during installation. Reversing the polarity of the live and neutral wire in an outlet can cause a shock or short circuit. Reverse polarity allows electricity to continue flowing into the appliance even when off.

A GFCI circuit can detect changes in power faster than a regular circuit breaker. Its primary role is to protect you and your family from electrocution. You can count on Huft Home Services for electrical solutions to keep your Sacramento home safe.

5. Breaker Trips Due to Outdated Wiring

Outdated wiring in your home could be another reason the circuit breaker keeps tripping. Older homes have electrical systems that cannot handle the electrical demands of a modern household. You can overload the circuit or trigger a fire by using the latest energy-demanding appliances.

One of the issues with outdated circuits is the absence of grounding connections. If you have two-pronged receptacles in your home, you may want to upgrade to a three-pronged outlet. The lack of a grounding slot can increase the risk of appliance damage or electrocution.

Aluminum wires in outdated electrical systems can melt due to circuit overloading. The plastic casing also increases the risk of a fire when it burns.

Additionally, deteriorating insulation on the conductor can trigger a ground fault. According to statistics, 90% of ground faults are caused by deteriorating insulation on wires and appliance cables.

6. Outdated or Worn Circuit Breaker

A circuit breaker can trip due to a loss of efficiency or a manufacturer’s defect. In such instances, the breaker may shut off the power even without the occurrence of a short circuit or overloading.

If your circuit breaker keeps tripping, schedule an electrical inspection. It is advisable to avoid tinkering with the breaker panel on your own. Consider consulting a certified electrician to prevent electrocution, fires, or appliance damage.

Certified electricians can pinpoint the problem in the shortest time possible. Professionals have the requisite training to handle complex and risky electrical projects. You can work with our team to plan an electrical system that suits your needs.

Circuit Breaker Keeps Tripping: Causes and Solutions

• One of the primary causes of a tripped circuit breaker is an overloaded circuit. This occurs when the total electrical load on a circuit surpasses its capacity. It can happen if you plug in too many devices or appliances into a single circuit. The excessive current flow triggers the circuit breaker to trip, preventing potential damage.
• A short circuit is another frequent culprit behind circuit breaker trips. It occurs when a hot wire comes into direct contact with a neutral or ground wire. This connection creates a low-resistance path for the electrical current, resulting in a sudden surge and tripping of the circuit breaker.
• Similar to a short circuit, a ground fault occurs when a hot wire comes into contact with a ground wire or a grounded part of an appliance or electrical system. Ground faults can be caused by damaged insulation or faulty wiring. When a ground fault occurs, the circuit breaker senses the irregular current flow and trips to prevent potential electrical hazards.
• Sometimes, a faulty appliance can trigger a circuit breaker trip. Malfunctioning devices can draw excessive current or cause a short circuit when connected to a power source. If you notice that a specific appliance consistently trips the circuit breaker, it’s essential to have it inspected or repaired by a professional.

Why does my electric keep tripping?

• Damien Heath
• 10th April 2023

Over the past few years, we have all relied on our home electricity supply more than ever. Whether you have been working from home since lockdown, or you spend your weekends in front of the TV, much of our day revolves around the use of electricity. However, with the increase in reliance, we have seen a significant rise in the number of clients contacting us and asking, ‘Why does my electric keep tripping?’.

If your power keeps tripping, then there are ways that you can resolve the issue without an electrician, and we have put together an easy-to-follow guide on how to perform this simple routine.

Why does my electric keep tripping? Causes, solutions & preventions

There are many reasons why you may be experiencing power trips, such as an overloaded socket or problems with the circuit; however, in most cases, the issue can easily be rectified without the need to contact an electrician. Nevertheless, as with any electrical-related problem, if you are worried about your electrical circuits and would prefer professional guidance before carrying out any tests, our team of electrical contractors in Milton Keynes will happily answer any questions you have. They can assess the issue over the phone and recommend the next steps you should take. In the meantime, here is our top advice on the following topics.

Why do my electrics keep tripping?

How to resolve an electric trip, how to stop power tripping.

Electrical circuits can trip for a variety of reasons, and we know better than anyone how frustrating it can be when it keeps happening. One common cause is an overloaded circuit, which occurs when too many appliances or devices are connected to a single circuit or socket, exceeding its capacity. This can cause the circuit breaker to trip or the fuse to blow, resulting in power loss and potential damage to your electrical system – this is common in a business setting due to the many appliances plugged into the sockets.

To prevent overloaded circuits, ensure that your electrical appliances are distributed across multiple sockets and are compatible with their capacity. Additionally, it is best to avoid using extension cables as a permanent solution for powering multiple devices, as it can create a fire hazard. If you’re unsure about the capacity of the electrical system in your office or are experiencing persistent tripping issues, our talented team of commercial electricians in Milton Keynes will be more than happy to help.

Another common cause of electrical circuit tripping is a short circuit, which can happen when wires within the circuit come into contact with each other or when an appliance has a fault. This results in a sudden surge of electricity, causing the circuit breaker to trip as a safety measure.

Another cause of tripping electrics occurs when a live wire comes into contact with a grounded surface, such as a metal fixture or water pipe causing a ground fault. Identifying the underlying cause of the tripping is essential to prevent potential safety hazards and avoid further damage to your electrical system. It’s always best to consult a qualified electrician if you’re experiencing persistent tripping issues.

Before contacting our team, we would always recommend completing the following steps; this will help you to determine whether the cause of the power trips is an appliance that needs replacing or an issue with the circuit itself. Follow the steps below or take a look at our “how-to” video for full instructions.

1. Find your consumer unit

The first step is to track down your consumer unit. In most properties, this is either in the cupboard under the stairs or in the garage.

Most homeowners have a dual RCD consumer unit, which means that there are two RCDs. If you are unsure what type you have, we recommend taking a look at our consumer unit page , which, if you scroll down on, you will find three examples of the most common options. Alternatively, we also have a full guide on what consumer units are and how they operate .

2. Checking the RCDs

The RCDs are the most likely component of your consumer unit to trip out, so you want to start by turning the RCD back on. If the power trips again after this, then you have a problem with your circuit.

In this instance, you will need to turn off all of the circuit breakers that relate to the RCD. The circuit breakers can be on the left or right side of the RCD, depending on what consumer unit you have.

Next, reset the RCD with the circuits off. If it does not reset, there may be an issue with the RCD itself. If so, contact one of our electricians if the RCD stays on.

3. Finding the circuit problem

To determine whether you have an issue with something plugged in, begin by taking a look at the switches on your consumer unit. You will see that each switch is labelled with what component it relates to, i.e. the cooker or sockets. The easiest route is to try the sockets.

Before testing the sockets, go around the house, switch off the plugs, and unplug everything connected to the circuit. In some cases, you may know exactly what circuit the switch relates to, so you will only need to do this on the sockets that connect.

Once sockets are off and appliances are unplugged, go back to the consumer unit – you should now be able to reset the RCD. If the RCD does not reset, contact an electrician to investigate the fault further. We have a reputable team of experienced electricians in Milton Keynes who are able to visit your home to rectify any circuit issues. Please do not hesitate to contact us if you require assistance.

4. Dealing with faulty appliances

If the RCD has reset, then this is an indication that the power trip may be caused by one of your electrical appliances. Begin by attempting to reset the RCD and following the steps above.

If resetting a particular circuit breaker causes the RCD to trip, the fault is most likely linked to this circuit. Leave the circuit breaker off and disconnect appliances or switch off connected equipment (i.e., unplug appliances) if the fault is socket related. Switch off light switches if it is lighting-related.

If you notice that when you plug any of the appliances on, it causes the power to trip, then it means that this is what is causing the issue. We would highly recommend replacing this appliance to prevent future tripping.

For those who have recently replaced their circuits or have good condition circuits but are still experiencing power trips, there are a number of ways that you can minimise the likelihood of losing power. These tips are straightforward lifestyle changes that you can make to prevent your power supply from overworking and include the following.

• Unplug any electrical appliances that are not in use; this will also help you to prevent wasted power and, therefore, save money on your energy bills.
• Consider how many appliances you have plugged into one socket. If possible, try to spread them across different outlets to avoid overloading the socket.
• Keep an eye out for any damage to appliances, such as frayed cords or scorch marks around the plug. We recommend replacing any damaged items before they have the chance to cause a danger.
• Be wary about using extension cords to power appliances that require a lot of power, such as TVs, as this can also be a culprit for overloading the main socket.
• Spend time understanding your amp usage, as this will help you to pair appliances with a socket that can withstand the electrical current they require.

Preventing power trips is as easy as that!

At Heath Electrical Services, we are dedicated to ensuring that our clients can enjoy long-lasting, reliable electrical installations by minimising the likelihood of an issue. We take an honest approach which means that if we feel that you can rectify the problem without our assistance, we will always share our knowledge on the steps to take. Finding and resolving the cause of regular power trips is one of the most straightforward electrical-related tasks that you can complete yourself, and we hope that we have been able to guide you in the right direction.

What’s Tripping My Circuit Breaker? 4 Possible Causes

As electricity flows through the wiring in your house,  circuit breakers  serve as critical safety devices that prevent overloads. When too many amps of electricity are pulled into a circuit, both damage and danger result. Wiring can overheat and melt insulation, causing a fire.

A circuit breaker is a more modern, reusable version of a fuse. The breaker constantly monitors the flow of electricity into a circuit, and if for any reason the amperage exceeds the circuit’s rated amount, the breaker trips and the flow of electricity is interrupted at the breaker panel. All outlets on that individual circuit and all devices plugged into it are instantly powerless.

How Much Load Is Too Much?

In a typical residence, circuits in living spaces like bedrooms and family rooms are generally rated for 15 amps. Parts of the home where more amperage is used such as the kitchen or laundry room will be controlled by more heavy-duty circuit breakers rated for 20 amps. Certain high-demand appliances, electric water heaters and central HVAC equipment will typically occupy an individual dedicated circuit and are rated for 30 to 50 amps.

While a tripping breaker is an important safety feature, it can be an annoyance as well, particularly if it happens often. A breaker that trips repeatedly is telling you something important about your home’s electrical circuitry or devices connected to it. Repeated breaker trips should never be simply reset and ignored.

Here are four common causes for a tripped circuit breaker.

Circuit Overload

A circuit overload, which is the most common cause of a breaker trip, occurs when a device plugged into the circuit demands more amperage of electricity than the circuit is rated to supply. This may occur because too many devices are already drawing current on that circuit and the circuit has reached its maximum rated capacity.

The remedy for circuit overload is to re-distribute the load more evenly by plugging some devices into other circuits.

Appliance Issues

Another may occur when a single electrical device draws excessive amps due to an internal malfunction or defect. For example, the electric motor incorporated in an air conditioner compressor may overheat due to internal wear and may pull too many amps. Or a heater or stove that utilizes electric resistance coils to produce heat may begin to cause overloads.

When a single device or component is causing breaker trips, it must be disconnected from the circuit and evaluated to isolate the problem. Repair or replacement of the device is required before it can be plugged back in and utilized safely.

Short Circuiting

A circuit short occurs when an insulated portion of the black “hot” wire physically contacts another black wire or a white neutral wire. This sends a surge of amperage into the circuit that causes the circuit breaker to trip instantaneously.

Short circuits may occur when household wiring degrades due to age and insulation frays or cracks, allowing bare wires to come in contact. Or it may be caused by an internal defect in any device that’s plugged into an outlet on the circuit.

Short circuits should be tracked to their source by looking for any discolored outlets, melted or cracked power cords or any devices that malfunction or emit a smell of burning wire. If obvious external causes can’t be readily identified, the problem is likely within the wiring itself. Leave the breaker switch off and contact a  professional electrician  to trace the problem.

Ground Fault

A ground fault happens when the hot wire in circuit contact either a ground wire or a grounded metal component such as the metal outlet box. A ground fault is simply another version of a short circuit that causes an electrical overload which triggers the breaker to trip in response.

Pinpointing and correcting a ground fault can be done by a qualified electrician using equipment specifically designed to troubleshoot circuitry.

During heavy rains, water makes contact into the cords, causing the circuit breaker to trip. It is essential to fix this problem as soon as possible since it becomes risky when water mixes with electricity.

Will a power surge trip a breaker?

A power surge occurs when there is an interruption in the flow of electricity. Therefore, a power surge can trip a breaker when the electrical current is high. In this case, the breaker trips to prevent electrical appliances from blowing up, which may also cause fires.

What are the three warning signs of an overloaded electrical circuit?

• Electrical shorts. An electrical short occurs when the circuit is highly overloaded since the power draw, on the other hand, is higher for the cable to contain. You will observe the breaker keeps on tripping.
• Discolored sockets. Accumulation of heat between the plug and it makes it hot hence it discolors the device. Note that you should not use discolored outlets. However, it would help if you had the sockets checked by electricians to examine and prevent further damages.
• Odors. Overloaded sockets produce an electrical burning smell. The smell is a result of heat emitted from the internal metal wires, which gets hot enough to melt the protective case. On detecting the odor, one should trace the source circuit that might be burning. You should take caution on this sign as the outer case can melt and generate fire.

How do you fix an overloaded circuit?

Upon identifying the circuit, ensure that you unplug the appliances plugged in and turn off any lights. Plug the electrical devices one by one.

This step will help you in identifying the machines that cause a trip. When you plug in everything without the circuit breaker tripping, then you have a potential overload.

How to Troubleshoot a Circuit Breaker Power Trip

Posted on 18 April 2022

Sometimes, circuit breakers can trip without warning. If your appliances or lights suddenly go out, it’s likely that one of your circuit breakers have tripped. If the entire house loses electricity, then it may be a power outage. However, if you only notice a few appliances and machines going out, you may want to take a look at your circuit breakers.

If you’ve never had to troubleshoot a tripped circuit breaker before, you may be overwhelmed by what you see on your electric panel - but don’t worry, there is an easy solution for fixing your circuit breakers! While you don’t absolutely need to be an emergency electrician Singapore to handle them, you might want to follow the tips below to ensure that you are fixing your tripped circuit breakers safely and effectively.

Locating the Circuit Breaker

Circuit breakers are the electrical switches that protect you from having to experience an electrical surge, or worse, an electrical fire. If the circuit breakers sense that there is an electrical surge, they will immediately shut off access to electricity so that you don’t harm yourself.

These circuit breakers typically resemble large, sideways ON/OFF switches. They can be turned off if you need to stop active electricity in your home. They are also used for repairs and upgrades. If you can locate your gray metal circuit breaker box - which is typically on the side exterior of your home or in a closet - then you can locate the circuit breakers.

Once you have found your circuit breaker box, you can open the metal panel and look for your switches, which should be in a long row. Even if some of your circuits look different, they should all function in the same way. If one of your circuit breakers has tripped, it will be switched in the opposite direction of the rest of your switches.

Resetting the Circuit Breaker

You can easily reset your breaker by following a simple set of directions:

• Recognize which breaker has tripped. Again, it will be the breaker that has been switched in the opposite (likely the “OFF”) position from all of the others (which are likely in the “ON” position).
• Turn off the appliances, machines, and lights controlled by the circuit. There should be some writing next to each switch which explains what part of the house it controls. For example, it may say “kitchen appliances” or “master bedroom”.
• Flip the switch back to the “ON” position. Make sure it aligns with all of the other switches in the row.
• Test that your reset has worked by turning on the lights in that area of the home.

Your tasks don’t stop there, though; you need to ensure that everything is in working order after you’ve flipped the switch back. If the breaker flips off again immediately, it means something is wrong and you must contact your electrician right away.

Warning Tips

Make sure to never touch or approach your circuit box if there is a wet floor . If there is any dampness around, you must stay away. You might be prone to electrocution or an electric blowout if you attempt to touch the circuit breaker when the floor is damp.

You should also ensure that you stop trying to flip the breaker if it keeps switching off. This means that you are dealing with a more serious issue, and you should seek the attention of a professional right away.

Most circuit breakers trip in the first place because they are drawing too much power for that area. If the power they draw exceeds the amperage rating of the circuit breaker, it will switch off as a safety measure. If this happens often, you might want to take a look around at how much power you’re using in that area and try to redistribute your plugged-in appliances around the home. Too many devices plugged into one area can cause the circuitry to overload, which will likely trigger the circuit breaker.
